Title: Improvements in piezo electric crystal assemblies
Inventor: SPEARS RALPH AUBREY
IPC: H03H9/10
Filed: 1949-05-27
Abstract: 661,614. Piezo-electric crystals. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. April 24, 1950 [May 27, 1949], No. 14207/49. Class 40 (viii). A piezo-electric crystal assembly comprises a number of plates 10 and 11, having metallic film electrodes deposited on their major faces, arranged face-toface with conducting spacing members therebetween, and held by spring clamps 15, the film electrodes leaving free a peripheral portion of each face along at least one edge, and the members being so disposed that each spacing member or clamp only makes contact with one electrode. In the example shown, the spacing members are two wires 16 and 17 which extend between opposite edges of the two plates 10 and 11 and extend down to connections to the contact pins 24. The assembly may be mounted in a sealed envelope 12 similar to that of a valve. If the film electrodes are staggered in their positions on the faces of adjacent crystals undesired capacity couplings are reduced. Alternative spacing members may consist of metal shields bearing ribs to make the actual contacts. Specification 524,167 is referred to.

Filed: 1953-05-21
Abstract: 762,278. Piling materials. JARUZA AKT.- GES. CHUR. May 21, 1953, No. 14261/53. Class 78 (4). Material is fed to a circular stock pile by a substantially radially disposed endless conveyer belt 6, Fig. 1, arranged both for endwise movement and for movement about the vertical axis of the stock pile for distributing the material. In the arrangement illustrated in Fig. 1 the conveyer 6 is carried by a supporting frame 8 at one side of a mast 7 and is capable of a longitudinal movement as indicated at 11 and of inclination as indicated at 12. A vertically moving counterbalance for the conveyer 6 is provided on the mast. Material is carried to the conveyer 6 by a fixed conveyer 3 fed by a bin 1 and discharging on to a helical shoot 5 disposed above the conveyer 6. The conveyer 3 can also deliver to a conveyer 4 carrying material away from the pile. Material is delivered from the pile through a conical chamber 13 which delivers to a conveyer 15 feeding the bin 1 so that the conveyers 3 and 4 may be employed to carry the material away. A scraper conveyer 18 may be employed to deliver material to the chamber 13 and may be raised and lowered by a cable 20 and winch 21 about a heel pivot carried by a platform 19 which is mounted for movement about the mast 7, as also is the winch 21. The conveyer 18 may be detached from its heel pivots and stowed in a vertical position on the mast 7. In alternative constructions the mast 7 terminates in suitable bearings on the lower side of the frame 8 so that the conveyer 6 may be disposed on the axis of the mast. If the conveyer 6 is not mounted for movement in a vertical plane it may deliver to a shoot suspended from the outer end of the conveyer frame and shaped to slow down the fall of the material. Walls 17 may confine the pile and the arrangement may deliver material to a bin which may be divided by radial walls into compartments. Where the conveyer 6 delivers to a bin it may be mounted solely by means disposed on the upper edges of the walls of the bin. In the construction illustrated in Fig. 8 a conveyer 33 is carried by a carriage 32 which moves along a slewing jib 30 and carries a spiral shoot 34 by which material is delivered from the conveyer 33 to a pile surrounding the mast 29 by which the jib is supported. Material is delivered to the conveyer 33 by a further conveyer 35 mounted in the jib and fed by a fixed conveyer which may alternatively deliver to a spiral shoot 36 carried by the mast.

IPC: E21F13/08
Filed: 1948-05-26
Abstract: 642,056. Conveyers. LOBBE, W. May 26, 1948, No. 14273. Convention date, July 2. 1947. [Class 78 (i)] A device for automatically shifting a conveyer in a plant for mining coal or the like includes a rigidly supported pawl mechanism operated by means of a wedge-shaped slide adapted to be drawn along the conveyer wherein a lever mechanism is mounted on the conveyer and is adapted to engage with the end of a rack which co-operates with a stationary locking device so that, as the wedgeshaped slide is drawn in either direction along the conveyer, it engages with the end of the rack and shifts the conveyer, and on moving further turns part of the lever mechanism through a small angle, whereby the rack is moved by an amount corresponding with the movement of the conveyer. The conveyer B which is made up of single sections receives material such as coal from a cutter D which has a laterally extending wedge 15 attached to a plate by a chain 14. Double arm levers 17, 18 are mounted on the conveyer, the adjoining ends of the levers engage recesses in the end of the rack 20 which has members passing on either side of the pit-prop 23 which is encompassed by a framework 24, 25, a member 24 engaging the teeth of a rack. The wedge when passing the rack is moved laterally, the arm 18 is moved to a position 18a and drags the rack after it, the arm. 17 moving to the position 17a. The next wedge, attached to the chain 14, also moves the conveyer laterally and drags the rack so that successive lateral movements may be obtained by a series of wedges. Only one double arm lever may be used for lateral movement in one direction of the conveyer. In an alternate form two hinged arms are mounted on a base-plate, such that when moying in one direction the conveyer is displaced and when moving in the opposite direction the arms collapse and no lateral movement takes place.

Title: Improvements in or relating to reeling control systems, particularly for the antennaand other parts of aircraft and the like
IPC: H01Q1/30
Filed: 1940-09-26
Abstract: 546,460. Winches. LEAR AVIA, Inc. Sept. 26, 1940, No. 14598. Convention date, Sept. 27, 1939. [Class 78 (v)] A remote control reeling system, more particularly for radio antennae of aircraft, has means whereby a plurality of specified lengths of wire can be paid out automatically to correspond with different reception or transmission wave lengths. The insulated reel or drum 11 may be hand operated, or driven by an electric motor 14, and the antenna 10 passes through a tubular fair-lead 12 for attachment by a swivel joint 36 to streamlined fish 13. A short length of aerial stretches beyond the " fish," and is permanently extended to allow of reception when landing and taking off. The control panel is shown at 18 and comprises a pointer 32 which, is adjusted over a graduated disc 31 to determine the length of wire it is desired to have exposed. This adjustment carries round a finger, which normally keeps open the motor circuit, through a corresponding arc, and thus by allowing the switch to close starts the motor. The latter, through a flexible enclosed cable 20, turns a worm engaging a wheel in frictional rotary connection with the switch finger, and thus gradually returns same till, when the required length of wire is out, it breaks open the switch and stops the motor. Means is provided for preventing actuation of the motor 14 till the craft has reached a certain air-speed, and this means may employ the pitot tube 29 normally fitted to air-craft. The air-pressure in a pipe 28.leading from the pitot tube controls a diaphragm-mounted contact in a switch 27. Lamps 37 are illuminated to indicate that the aerial is partly or wholly extended, and are extinguished when the wire is fully wound in, the control switch 34 being automatically actuated. The fair-lead tube 12 encloses a telescoping portion' terminating in a fluted bell orifice 21 which receives the " fish" 13, a spring 68 giving the bell a slight elastic yield to less jar when the " fish" returns. Two forms of fair-lead are described, and the reel 11 may be enclosed to reduce flailing of the wire should the antenna break while extended and the " fish " be lost. The radio set 25 is located near the reel 11 and adapted for distant manipulation. A switch 33 cuts out the motor and determines which direction current shall flow therethrough when energized.

Abstract: 877,219. Blending powders. COX, R. L. April 14, 1960 [April 29, 1959], No. 14676/59. Class 86 An apparatus for blending granular and pulverulent materials comprises a vertical column divided into three zones 2, 3, 4 by two rows of orifices 14, 17 each surrounded by an annular chamber supplied with pressure gas by pipes 15. The orifices are oppositely directed, see Figs. 2 and 3, along tangents to a circle of diameter about twothirds the diameter of the column. The material to be mixed or blended is induced into a stream of pressure gas and injected tangentially at the top of the column as by the Venturi injector 6; its direction of movement round the column is twice reversed as it falls past the two rows of orifices. The material is collected in a hopper 18, the gas being discharged through the filter 19. In a modification (Fig. 4 not shown), the injecting Venturi is formed as a coaxial extension of the upper end of the mixing column, so that the material is not rotating when it enters the first mixing zone 2; the two rows of orifices are formed as vertical slits in the walls of the column, and are surrounded by a common gas chamber.

Title: Improvements in the electrolytic coating of metals with other metals
IPC: C25D19/00
Filed: 1932-05-26
Abstract: 404,972. Electrodeposition of metals. COLES, S. O. COWPER-, and FERBRITE, Ltd., Rossall House, Thames Street, Sunburyon-Thames. May 26, 1932, No. 14917. [Class 41.] Detached metal plates or sheets are mechanically conveyed through an electrodeposition bath at such a speed that the interval between immersion and emergence of any point of a plate or sheet does not exceed one minute and is preferably less than half a minute ; a currentdensity of at least 200 amps per sq. foot is employed. Electrical contact is made with the plates by means wholly external to the bath such as feed-rollers. As an example, a sheet measuring 28 inches by 20 inches may be passed through the bath in 4 seconds. The feed rollers are so arranged that a sheet is engaged by a fresh pair before release by the preceding pair. The position of the rollers may be adjusted. Anodes of lead or ferrosilican may be employed. The invention is particularly applicable to the coating of iron or steel plates with zinc or zinc alloys. The plates may be passed through a succession of depositing baths and may be subjected between successive baths to mechanical treatment such as abrasion or burnishing by transversely reciprocating brushes. The deposit may be consolidated by rolling preferably by a succession of lightly loaded rollers. The feed-rollers may be employed for this purpose. The rolling in the case of zinc may be carried out at a temperature of 80-100‹ C. and the rollers may be heated for this purpose. Before plating the plates are pickled by cathodic treatment in hydrochloric or sulphuric acid. The plating electrolyte is circulated through a filtering tank containing ground coke or silica and a regenerating tank containing scrap or granulated zinc, zinc residues or zinc oxide. A group of cells may be connected to a single filtering and regenerating system. The coated plates may be corrugated or may be further coated by enamelling or the like or by electrodeposition of rubber.
